Last updated: 12 November 2026
This policy explains how Delta Engines Ltd collects, uses and protects your personal information when you use this website, request a quote, or become a customer. We keep it deliberately plain: we collect only what we need to quote for and carry out engine work, we never sell your data, and we never use it for third-party marketing.
1. Who we are
Delta Engines Ltd is the data controller for the personal information described in this policy. We are registered in England and Wales under company number 12702487, at Unit 15D Askew Farm Lane, Grays, Essex RM17 5XR.
For anything relating to your personal data, contact us on 02033 180532 or 07902 539094, by WhatsApp on +44 7936 418074, or at support@deltaenginesltd.co.uk.
2. What we collect and where it comes from
When you request a quote — through our quote form, the registration lookup, by phone or by email — we collect your name, phone number, email address, postcode, and details of your vehicle and the work you need.
When you use the registration lookup on our website, you enter your vehicle registration number. We send it to the Driver and Vehicle Standards Agency (DVSA) through its MOT History service, which returns the vehicle’s make, model, year, first registration date, engine size, fuel type and colour, together with its MOT test history (test dates, results, recorded mileage, and any failure or advisory notes). On the website we show you only the vehicle description. If you send us an enquiry, the full record is attached to it so we can identify the right engine and quote accurately. The DVSA does not give us the registered keeper’s name, address or any other personal details. If you do not send us an enquiry, we do not keep your registration number: the vehicle details are held briefly (no more than 24 hours) so that a repeat lookup does not query the DVSA again, then deleted automatically. To prevent misuse of the lookup, your IP address is also held in coded (hashed) form for up to one hour to limit the number of lookups. A registration number linked to your enquiry is treated as part of your personal data.
When you become a customer, we additionally hold your address, vehicle details, job records, invoices and payment records. We do not store full card details — card payments are processed by our payment provider.
When you browse the site, we collect limited technical data (pages visited, device and browser type, approximate location derived from IP address) through cookies, described in section 8.
We do not knowingly collect data from children, and we do not collect any special category (sensitive) data.
3. How we use your information and our lawful bases
Under UK GDPR we must have a lawful basis for each use of your data:
- To prepare and send your quote, and to answer your enquiry — necessary to take steps at your request before entering a contract.
- To carry out the work, invoice you, and administer your warranty — necessary for the performance of our contract with you.
- To keep accounting and tax records — necessary to comply with our legal obligations.
- To follow up on a quote we have sent you, and to improve our website and service — our legitimate interests in running the business, applied in ways you would reasonably expect. You can ask us to stop follow-ups at any time.
- Analytics cookies — only with your consent, given through the cookie banner.
We do not send marketing emails or newsletters. If that ever changes, we will only do so with your prior consent, and every message will include a working unsubscribe link.
4. Who we share your information with
We share personal data only where necessary to do the job:
- the Driver and Vehicle Standards Agency (DVSA), through its MOT History service, which receives only the registration number you enter into our lookup tool in order to return your vehicle’s details and MOT history;
- parts suppliers and couriers (delivery details for parts or engines);
- our payment provider, to process card payments;
- our IT, hosting and email providers, who process data on our instructions under contract;
- our accountants, for statutory record-keeping;
- HMRC, regulators, courts or law enforcement where we are legally required to.
We never sell or rent your personal information, and we never pass it to third parties for their marketing.
International transfers. Some of our service providers — including Google (Analytics, Tag Manager) and Hotjar — may process data outside the UK, including in the European Economic Area and the United States. Where they do, the transfer is protected by UK adequacy regulations (including the UK–US Data Bridge) or by International Data Transfer Agreements / standard contractual clauses, so your data receives an equivalent standard of protection.
5. How long we keep it
- Registration lookups without an enquiry: vehicle details deleted automatically within 24 hours; lookup-limit records within one hour.
- Enquiries and quotes that don’t proceed: deleted or anonymised within 12 months of our last contact.
- Customer job records, invoices and warranty records: kept for 6 years after the end of the tax year they relate to, as required for tax purposes and to honour warranties.
- Website analytics data: retained per the settings described in section 8.
Backups are cycled on a fixed schedule, so deleted data may persist in encrypted backups for a short period before being overwritten.
6. Your rights
You have the right to:
- access a copy of the personal data we hold about you;
- correct anything inaccurate or incomplete;
- erasure of your data where we no longer need it;
- restrict or object to our processing, including any based on legitimate interests;
- data portability — receive your data in a common machine-readable format;
- withdraw consent at any time, where consent is our basis (for example, analytics cookies).
Exercising any of these rights is free of charge. Contact us using the details in section 1 and we will respond within one month. We may ask for information to verify your identity before acting on a request.
If you are unhappy with how we have handled your data, you can complain to the Information Commissioner’s Office (ICO) at ico.org.uk or on 0303 123 1113. We would appreciate the chance to resolve your concern first.
7. How we protect your information
This website is served over HTTPS, form submissions are encrypted in transit, and access to customer records is limited to people who need it to do their jobs. No internet transmission can be guaranteed absolutely secure, but we take the security of your data seriously and review our measures regularly.
8. Cookies
Cookies are small text files stored on your device by your browser. We use:
Essential cookies — required for the website to function (for example, remembering your cookie preferences and enabling the quote form to work). These do not require consent and cannot be switched off.
Analytics and improvement cookies — set only if you accept them in the cookie banner, and you can change your mind at any time using the cookie settings link in the footer. We use:
- Google Analytics (GA4), loaded via Google Tag Manager, to understand how visitors use the site — pages visited, how you found us, and general (not precise) location. Data is aggregated and we do not use it to identify you.
- Hotjar, which helps us improve the site through anonymised heatmaps and session recordings showing how visitors move around pages. Hotjar masks keystrokes and personal data entered into forms, and we do not use it to identify individual visitors.
We do not use advertising or social media tracking cookies.
Websites we link to set their own cookies under their own policies, which we don’t control.
9. Changes to this policy
If we change this policy, we will publish the updated version here with a new “last updated” date. Significant changes affecting how we use your data will be flagged clearly on the site.
